CORS 阻止子域名报告 js window.onerror 信息

CORS 阻止子域名报告 js window.onerror 信息

为了记录 Javascript 错误,我设置了一个带有 window.onerror 的函数,该函数会触发 ajax 请求并通知我有关脚本错误的信息。我从子域加载所有静态文件,如果主域之外的文件发生错误,CORS 似乎会因为泄漏而删除信息... https://developer.mozilla.org/en-US/docs/Web/API/GlobalEventHandlers/onerror#notes

我尝试通过设置 Access-Control-Allow-Origin 来解决该问题:

add_header Access-Control-Allow-Origin https://static.example.com;

但没有成功。

我的子域名也带有与主域名相同的 Access-Control-Allow-Origin。

如果服务器发送的响应带有Access-Control-Allow-Origin显式来源的值(而不是“*”通配符),则响应还应包括各不相同响应标头的值为 Origin — 向浏览器指示服务器响应可能根据 Origin 请求标头的值而有所不同。

Access-Control-Allow-Origin: https://developer.mozilla.org
Vary: Origin
